As these gangs are of each other from the upper to the lower ends the ordinary construction theywill not be speof said terminals. Through the bolt-openings cifically described, the numeral 1 being emin the terminals a transverse-bolt 18 is passed ployed to designate the beams, to the front the ends of the bolt extending beyond the ico 5o ends of which (devis-plates 2 are secured. terminals some distance, and a spacing-sleeve Each beam also carries a plate 3 in rear of its or tube 19 is mounted upon the bolt between upon the exterior of the aforesaid terminaL' and hence is maintained against lateral movement independent of said yoke.

yokes of t-he movements and hence the ,cultivators adapted to .run deep or shallow as lthe case may be.

A nut 32 is secured upon the innerthreaded end lof the transverse-bolt-that passes Ithrough 3 the yoke, and over said nut there is mountedplate 33 which is provided upon its inner face witha countersunk recess 34 conforming to the shape of the nutrand adapted to prevent any' turning 0f the same; and upon its outer face a hang-up supporting nut -receiving Wit-l1 an inclined shoulderor rest 35. An arm 36 is mounted on the bolt outside ofthe locking-plate, and a nut 37 occupies the outer end of the bolt and bears against the arm. This arm is provided at its outer or free end with a notch or lhook 38, andisadapted to serve as a hang-up device for engaging the link of the beam of that gang that is immediately in rear thereof, whereby said gang is supported in an elevated inoperative position, at which time-the aforesaid hang-up arm rests against the incl-ined shoulder of the locking-plate. 1t will thus be seen that upon asingle bolt there is secured the yoke, the hang-up supportingplate which also serves as a nut-lock, the hang-up arm, theaxle, the extension supporting arm, and the locking-plate.

The inner terminal 14 of the yoke is provided near its front edge with a slot 40 in which engages a bolt 41 which extends forwardly to a point opposite the front end of the arm or bar that supports the extension, and to this plate ,and .arm there are pivoted by bolts 42 draft-straps 43, whose fron-t ends loosely coupled vor .swiveled together, :each

.draftanirnal ,performs his own share `of the work, and draws that gang in front of which the vis hitched.

Each of lthe terminals of the `yokes is provided with a rearwardly-extending bracket 44 having circular openings surrounded by ,annular bosses ,or llianges 46. The :said perforations are provided near their front Aends with lugs 48 and :the brackets .are provided on /thei r rear ysides V.with eccentric lugsor teeth 49. The :cultivator-beams have vertical ,slots `51 .at their frontends, in which yare seated the coupling-plates 52, the `upper and lower edges of which are provided `with ianges itobear against the ,npperand lowersides ofthe beams, 29 designates a locking-block or p iate, the

ingianms 55 which are connected by the ver-y tical `:pifnsor bolts 56 to form clevises. These clevises are connected with the draft ,brack- .ets of the yokes by means of .fthe beam Icoupling-plates, each of which is provided ywith a laterally-,extending boss 56a -to engage the tia-nges 46 of the draft-brackets. VThe boss 56a of the plates, .which latter-:are designated as 57, are provided with notches 58 1D0-engage the lugs 48 formed in the perforations 47 of said draft-brackets. The .coupling-plates .57 are provided with ,transverse perforations 5.9 and 60, the former of which extends through the boss :56aand :the latter lof which extends transversely in rear .of said boss. Consequently lthe .couplingbolt 61, which passes through the perforation 60 will normally rest upon the eccentric lug or tooth 49 `of the draft-bracket. Th'elmeetingfaces of the coupling-plates are provided at their rear ends with vertical grooves 62- designed to receive the vertical pinsor bolts 56 of the clevisesat the front ends of the cultivator-beams. It

will be seen that by tightening the coupling- IIO bolts and 63 respectively the parts may be firmly connected in such a manner as to permit the cultivator-beams to swing or oscillate both laterally and vertically, thus connecting the said cultivator-,beams with their respective movements by universal -joints, which Joints are greatly simplified and strengthened in their constructions over those illustrated, described, and clailned in myprevious patent above referred to. At the same time it will be observed that the movement in a downward direction of the cultivator-beams will be limited by the said lugs 56 which engage with the bolts 6l and by the boss 56a engaging the lugs 48, as hereinbeforedescribed.

The bolts that connect the coupling-plates with the brackets at the rear sides of the yokes are provided with nuts which are located in line with each other. A plate 66 is located between the bolts and provided at its upper and lower ends with cross-heads or lugs 67:, which prevents a Withdrawal of the plate without an entire removal of the bolts. The

plate is provided upon its outer side with a central lug 68, and when the plate is loweredv between the bolts the lug takes between the adJacent faces of the nuts and prevents any movement of the same. This plate serves as a rigid locking device for the nuts, which in the position it occupies is very important, in that it permits of a ready removal of the nuts for the purpose ot' readjusting the beams to the coupling-brackets.

From the foregoing description in connection with the accompanying drawings it will be seen that I have greatly simplified and improved the construction of the cultivator over that hereinbefore set forth in my previous patent and yet at the same time I preserve all the advantages existing in the aforesaid construction in that I secure an independent hitch or attachment, Without losing direct control of the gangs; I provide for the attachment of the hitch to the point of a beam without the medium of a doubletree; the gangs in operation move not only independent of each other but back and forward in the line of progression and always at the same distance apart,which distance maybeadjusted there is no side draft and consequently no drifting of the gangs in a lateral direction; the machine may be turned in the shortest possible space; cannot fall down or become entangled in the operation; and finally, the gangs or beams are so constructed and arranged that they may be managed ormanipulated very easily and conveniently. It is furthermore to be observed that by loosening the set-screws in the end of the arch and turning both wheels under the arch, the said wheels run side by side in the furrow at the sides of the corn, thus admitting of the independent use of each gang against the ridge on each side of the listed-corn row.

'Ihe employment of my cultivator in the operation of cultivating listed-corn is considerable of an advantage, as in working the side or ridge next the corn-row you hill up next the corn and form water courses on each side of the row and furthermore you may cover the Weeds to a better advantage and with more success. understood that the gangs are made rigid with the arch. y

Having described my invention, what I claim is- In such work it will be 1. In a cultivator of the class described, the i combination with the opposite gangs and their movements, of vertical spindles rising from the movements, inverted L-shaped tubular standards mountedV loosely onL the spindles,
